Multilayer Ceramic Chip Capacitors
GMC SERIES
Introduction
Multilayer Surface Mount Ceramic Capacitors are constructed by screen printing alternative layers of internal metallic
electrodes onto ceramic dielectric materials and firing into a concrete monolithic body, then completed by application of
metal end terminations which are fired to assure permanent bonding with the individual internal electrodes.
Multilayer ceramic capacitors have various features such as large capacitance values in small sizes and excellent high
frequency characteristics.
Moreover, chip capacitors can be used on surface mount assembly equipment. Our fully integrated manufacturing and
total quality control systems ensure unprecedented high standards of quality and reliability.
Chip Capacitor Selection
Selection of the most suitable capacitor for any application is based on the following:
omDielectric Type
The choice of dielectric is largely determined by the temperature stability required.
.cCOG (NPO)
UCapacitance change with temperature is 0-30ppm/°C which is less than -0.3%°C from -55°C to +125°C. Typical capacitance
change with life is less than -0.1% for NPOs, one-fifth that shown by most other dielectrics. NPO formulations show no aging
t4characteristics.
X7R/X5R
eIts temperature variation of capacitance is within ±15% from -55°C to +125°C (-55°C to +85°C for X5R). The capacitance change is
enon-linear.
Z5U
hDespite their capacitance instability, Z5U formulations are very popular because of their small size, temperature range low
SESL, low ESR and excellent frequency response. These features are particularly important for decoupling application where
only a minimum capacitance value is required.
taY5V
aY5V formulations are for general purpose use in a limited temperature range. They have a wide temperature characteristic
of +22% - 82% capacitance change over the operating temperature range of -30°C to +85°C. Y5Vs high dielectric constant
allows the manufacture of very high capacitance values (up to 22MF) in small physical sizes.
.DCapacitance Value & Tolerance
wDetermined by circuit requirements. Note that chip prices decrease with lower capacitance value and looser tolerance.
Voltage
wDetermined by circuit requirements. Units are designed to exceed the withstanding voltage specification, i.e., the user need
w mnot incorporate an additional safety margin.
.coCapacitor Size
t4USelect the smallest unit permitted by the circuit constraints that provides the required capacitance and voltage rating.
All Cal-Chip capacitors conform to EIA specifications.
heeCapacitor Termination
STermination choice is largely determined by the chip attachment method. Silver-palladium is adequate for most applications
tainvolving soldering or solder reflow.
aNickel barrier is standard and recommended for units exposed to repeated solder cycles, to minimize leaching of the ter-
